Comment(by michalt):
I've built GHC with the new patch on x86_64 and it doesn't introduce any
failures in the testsuite. :)
As for the negative zero I have absolutely no idea whether it's really
important. Though functions having different results with and without
optimisations make me feel uneasy.
